I was wondering how to safely convert a Hybrid GPT/MBR to a pure GPT partition scheme? (Without Reformatting)
The reason why I ask is, I currently triple-boot with Ubuntu 16.04 LTS, Windows 10 and Mac OSX Lion.
Originally I needed to format my drive with a Hybrid partition scheme to install Windows 7 but I have since upgraded to Windows 10.
I know now that Windows 10 supports booting from GPT partitions and I would like to covert everything to a pure GPT partition scheme without reformatting.
If I can do this, I would be able to reformat my HFS+ partition to an APFS partition and install High Sierra.
So the questions are:
- How do I convert my Hybrid MBR to a pure GPT?
- Will it break booting into any of my OSes if I do? (Windows 10, Linux, MacOSX)
Here is my gdisk output:
